Subject: [PATCH] media: i2c: tvp5150: Fix horizontal crop stop boundry
Date:   Tue, 17 Sep 2019 09:14:42 +0200
Message-Id: <20190917071442.24986-1-robin@protonic.nl>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The value for AVID stop is relative to the width of the active video area,
not the maximum register value. Zero means equal and a negative value means
we're cropping on the right side.
